This lesson mainly teaches the decision flow: choosing between two real mill options for the same fabric, using the machine facts from lessons 5.1 to 5.3 rather than which mill called first. A factory or brand often has more than one mill that could plausibly supply a fabric; the choice between them should follow from comparing quantity, lead time, width and patterning ability against the order's own requirement, not from habit.
This matters to Omar, the owner of Cedar & Co., who is deciding between two mills for a domestic knit reorder, and to Mona, the merchandiser at Delta Garments, comparing an export denim sample against Order B's own established route. A person who picks a mill without comparing these fixed limits risks a quantity or lead time mismatch discovered only after the order is placed.
Without this skill, a person defaults to the mill they know best, even when a different mill's own machine type actually fits the order better, and only finds out the mismatch once it is too late to change course cheaply.
You need: no previous lesson is required, though lessons 5.1 to 5.3 make the comparison method here far easier to apply.
By the end of this lesson you can:
Not covered here: the machine families themselves (lesson 5.1), specialised sock and towel machinery (lesson 5.2), and how machine choice shapes what a factory can source (lesson 5.3).
| Term | Meaning |
|---|---|
| Minimum order quantity | The smallest amount a mill will accept or process as one order, which a calculated yarn requirement is often rounded up to. |
| Lead time | The total time from a confirmed order to the goods reaching their destination. |
| Fabric width | How wide a fabric comes off the loom, usually stated in inches or centimetres, separate from EPI and PPI. |
| Circular knitting machine | Knits a seamless tube of fabric, or a complete sock, on a rotating cylinder of needles. |
| Air-jet loom | A shuttleless loom carrying weft yarn on a jet of air; the fastest common loom for plain or twill fabric at volume. |
Two mills can both plausibly supply the same fabric, and still be the wrong or right choice for a specific order depending on their machine types. The comparison always runs the same four checks: can this machine meet the order's quantity without an unnecessary cost premium, does its lead time fit the delivery date, does its width suit the marker, and can it add any patterning the order needs. A mill chosen out of habit, without running these checks, may fail on any one of the four even though it has supplied the factory or brand successfully before on a different order.
| What can differ | The shapes you will meet | Why it matters |
|---|---|---|
| A domestic Make to Stock reorder for a local brand, such as Cedar & Co.'s knit fabric reorder | Compare Rowad Knits' ordinary circular knitting lead time against a faster mill sized for smaller runs, against the reorder's own quantity and timing. | A domestic reorder still needs the same four-point comparison; "we always use this mill" is not itself a reason if the quantity or timing has changed. |
| An export sample or small pre-production run, such as a denim sample using Order B's own 3x1 twill route | Compare against Suez Denim's own established minimum and lead time for that construction, since a sample quantity may sit below the mill's efficient batch size. | A small sample can carry a cost premium the four-point comparison should surface before it surprises the buyer's costing. |
| A hybrid order combining a confirmed export quantity with a domestic top-up, a shape Cedar & Co. and Delta Garments both use at times | Run the four-point comparison once for the combined quantity, since splitting it across two mills may cost more in combined minimums than running it through one. | Confirms the comparison is run against the order as actually placed, not against an assumed simpler shape. |
| A specialised product needing lesson 5.2's own machine, such as a sock or towel reorder | Compare only mills running that specialised machine; a general knitting or weaving mill is not a valid option regardless of price. | The four-point comparison only applies among mills that can physically produce the shape at all. |
| Two mills quoting similar price but different lead time | The four-point comparison surfaces the lead time gap directly, rather than leaving it hidden behind a price-only comparison. | Price alone does not reveal whether either mill's machine can actually meet the delivery date. |
| A mill that supplied a factory well on a past, different order | Still requires the same four-point comparison for the current order, since a different quantity or width can put it outside that mill's own fit even though the relationship is good. | Past performance on a different order does not substitute for checking today's actual requirement against today's mill options. |
Omar needs a domestic reorder of single jersey knit fabric matching Order A's own construction for Cedar & Co.'s 12 shops. He compares Rowad Knits' ordinary circular knitting lead time against a second knitting line at Suez Hosiery that runs faster but is sized for smaller runs, checking each against the reorder's own quantity and delivery timing rather than which mill Cedar & Co. has used most often. Separately, Mona at Delta Garments compares a denim sample request against Suez Denim's own established 3x1 twill route, checking whether the sample's small quantity fits under Suez Denim's usual minimum before assuming the standard denim lead time applies unchanged. Both comparisons use the same four points; only the fixed order and the mills being compared differ.
The worked numberThis lesson's worked output is a side-by-side comparison, not a single cost figure, since the skill is comparing two real options against one requirement.
A common mistake is assuming that a mill which performed well on a past order will automatically fit the current one, without re-checking quantity, lead time, width and patterning against the current order's own figures. A mill's machine type has not changed, but the order has: a reorder quantity, a tighter delivery window, or a new fabric construction can put a previously reliable mill outside its own fit for this particular order, and only the four-point comparison, run again, catches that.
Choosing between two mills for the same fabric is not about which one a factory or brand likes better or has used more often. It comes down to four plain questions, asked of each mill in turn: can it make the quantity, can it deliver on time, does the fabric come out the right width, and can it add any pattern needed. A mill that answered all four well on a different order in the past might not answer them all well this time, if the quantity, timing, width or pattern need has changed. Running through the same four questions every time, instead of trusting habit, is what finds the mill that actually fits the order in front of you.
Omar, the owner of Cedar & Co., needs to place a domestic reorder of single jersey knit fabric for his 12 shops before the brand's restocking window closes.
The note Omar reviews, side by side:
Should Omar reorder from Rowad Knits out of habit, or run the four-point comparison against Suez Hosiery's knitting line first? Decide before opening the answer.
Run the four-point comparison first. This reorder's smaller quantity and tighter window are exactly the figures that can shift which mill actually fits, regardless of past habit.
First fact. Rowad Knits has fit past, larger restocks well, but this reorder's quantity is smaller and closer to what Suez Hosiery's line is sized for.
Second fact. The delivery window is tighter than usual, which favours whichever mill's real lead time, confirmed today, actually fits, not whichever mill fit a past, looser window.
Reordering from Rowad Knits purely from habit risks missing the tighter window if its ordinary lead time no longer fits this smaller order's own timing, when Suez Hosiery's faster line, sized for exactly this kind of smaller run, may be the better fit this time.
Framed qualitatively, since this lesson teaches a comparison method rather than a single cost calculation: reordering from a habitual mill without checking today's quantity and delivery window against its real figures risks a missed restock date for a domestic brand's shops, which costs lost sales during the window the stock was meant to cover. The same risk runs the other way: choosing an unfamiliar mill without confirming its own limits, such as the fabric width Suez Hosiery's line would need re-checking, risks a fabric that does not fit the factory's own marker, a costly discovery after fabric has already been cut. Running the four-point comparison before ordering costs nothing beyond the time to ask each mill the same four questions.
Open the Mill machinery reference guide. On the Decide sheet, enter your own order's quantity, delivery timing, width and patterning need, then check each mill option against the same four points the way this lesson compared Rowad Knits against Suez Hosiery's knitting line for Cedar & Co.'s reorder. Record any unconfirmed point before finalising the choice. Download link: `templates/T08-C05-mill-machinery-reference-guide.xlsx`.
1. Why should Omar not simply reorder from Rowad Knits out of habit for Cedar & Co.'s current reorder?
2. What does the four-point comparison check for each mill option?
3. A factory needs a small pre-production sample from a mill whose usual minimum order quantity is much larger than the sample. What should the four-point comparison flag?

You can now name a mill's main machine families, recognise specialised sock and towel machinery, read what a mill's machine choice lets a factory source, and choose between real mill options for a real fabric or product family, using the same four-point comparison every time. Back to the course map
